Geography The Atacama Desert
Chile's Atacama Desert is Earth's driest place, with some areas receiving no measurable rainfall in recorded history. The extreme aridity results from being in a rain shadow between the Andes and Chilean Coast Range, with cold Pacific currents preventing cloud formation. Despite the harsh conditions, microorganisms survive, making the Atacama a testing ground for Mars exploration techniques and understanding life's limits.
